The guest room was opened because it was occupied, and the air seemed to have a layer of gray, and the light came as if covered with a veil.

Although Ren Yifei scared the audience just now, he did suspect that there was a third person hiding in this room, but it was last night, and now the other party is estimated to have left.

The killer was very careful not to touch anything, but Ren Yifei found some traces.

"look at this."

The live fly pointed at that place, and then saw several shallow scratches that landed on the light gray wall, which could not be found without careful search.

"he was looking for this wall on purpose." Ren Yifei said, "guess why?"

The viewers in the studio watched for a long time and saw that there was something special about the wall.

"at the other end of this wall is the crouching. If you stand close to the wall, you can hear the noise of lying on the other end of the wall. Please give us a demonstration. "

He leaned his back against the wall and stuck it there: "Last night, the killer might have been standing here, listening to the laughter at the other end of the wall, and his hands scratched the wall with consciousness." If you take a closer look at this scratch, you can see the direction. Because the killer is about the same height as the beetle, in theory, his scratches are at the same level as the beetle's fingers. "

After fixing his arm, he leaned over and looked, sure enough, at the same level as his hand.

"well, the characteristics left by the killer are too similar to those left by the deceased's boyfriend, and there is still a way to prove the innocence of the deceased's boyfriend." Ren Yifei frowned and frowned at the word 'Sichuan'.

"give up, you are the murderer." The viewers in the studio booed, and just now they were scared enough. Now, facing this Xiaojun face, they feel like they want to be taught a lesson.

The guest room is not big, except for a walled wardrobe, an empty double bed and a nightstand of the same style, everything else is available at a glance.

But he still examined it carefully and wanted to take out a magnifying glass.

Because the killer was very careful, he was expected to return with great success this time, but when he opened the nightstand drawer, he found a surprise-the huge green plant sealed in the crystal ball, which is the symbol of the wooden capital.

"well, it's not nothing." Ren Yifei thought.

He rummaged through the drawer full of long-forgotten things: a crystal bracelet, headphones, a heart-piercing key chain with a crystal diamond, and an old photo.

He opened the old photo and found that it was a picture of the deceased in his student days, with a certain medical college in the background, and the deceased was standing with a tall, short-haired girl. The deceased was wearing a light-colored skirt and red high heels, and a girl with short hair was wearing jeans and cloth shoes with flat soles.

The height of the deceased is about 1.6 meters, with an error of no more than three centimeters, and this girl is half a head taller than her. minus the height of high heels, the girl should be between 1.75 and 1.8 centimeters.

Ren Yifei touched his chin and began to have wonderful associations. But he felt that he didn't jump to conclusions. He just stood up and opened the wardrobe.

The wardrobe was basically empty, except for a bulging travel bag below. Ren Yifei opened it and took out the clothes one by one.

Men's shirts, jeans and casual pants are colder and less saturated. If you look at the size, it is suitable for people between 1.75 meters and 1.8 meters tall.

Of course, this still doesn't mean anything, what if it's old clothes from the original clothes? But Ren Yifei soon found new evidence that the clothes belonged to a girl.

"how about a corset?" It's not the kind that's wrapped so tight, it's a little curved, and you can see that it's a woman's product.

"that is to say, in this room, there once lived a girl who was between 1.7 and 1.8 meters tall, often dressed as a man, uncertain, but had a good relationship with the deceased and had known her since college."

Ren Yifei whispered to the live fly, clutching his chest at the same time: "I don't know why, I'm a little nervous now. I always feel like I'm going to discover a new world."

There were more discoveries in the guest room, and Ren Yifei went back to lie down. The body still opened its eyes wide and died in grave, and the audience once again felt the depression brought by the mosaic.

Ren Yifei re-covered the deceased with a pillow towel and then took the deceased's mobile phone.

Probably in order to facilitate the contestants to inquire, there is no password inside, click to open.

He focused on the information in the victim's social account.

"this is the purchase discount group, this family group, this is the company small group. It makes it look like an impressionist. " He thought about it and went straight to the classmate group, but the students basically didn't use their faces as their avatars.

"you can use your cell phone to ask for help and look for clues." This is the message left by Officer Liu before he asked for help. Ren Yifei was reading "looking for clues with his cell phone" when he suddenly thought of something.

After a while, he went to fetch old photos, take pictures, and then send a message to one of the most chatting girlfriends-like characters.

"Ding Dong." I'll be back in a second over there.

"come on, sister, you're getting married, and you can't forget her?"

The viewers in the studio saw the yawning spirit of Ren Yifei in an instant, holding a mobile phone in both hands and carefully sending one: "Ah …". "

There was no need for him to say more after the accident, and npc began to dutifully deliver clues.

Through the complaints and advice of his best friend, Ren Yifei probably understood what was going on. When the deceased was in college, he fell in love with a rich and handsome sister from the next department, and the two quarreled on and off for many years.

Later, after graduation, the deceased returned to his hometown and went to work as a nurse in a private hospital. The handsome girl also came, and the two of them lived together for a period of time.

But six months ago, I didn't know if it was the family or the deceased themselves, and they broke up.

It is said that the quarrel was particularly serious, and economic disputes were also involved, because the handsome girl spent a lot of money on the deceased over the years.

But in the end, they broke up and got in touch with each other again.

After the accident, the deceased found the present one, probably known by the hospital, and talked about marriage.

"is it always that risky to fall in love these days?" Ren Yifei wiped a cold sweat. The dead, even if they did something wrong, were not guilty of death, and they had broken up for half a year.

Something must have happened that led to the outburst of negative feelings of the deceased's ex-girlfriend and could not be stopped before such a terrible thing happened.

What could it be?

He found his ex-girlfriend in his contact. Ooh, the deceased blocked her and deleted all the conversations before her.

Ren Yifei pulled the ex-girlfriend back and opened each other's moments, only to find that the sister was still celebrating her birthday the day before yesterday. The cupcake for one person lit a candle.

In the photo, she is holding a cake in her hand, and her short silver-gray hair with black roots is sticking up at random. There was a smile on her face. don't know if it's the lens, but her eyes are still a little red.

Their mutual friend left a message below: happy birthday, looking for something.

The deceased's ex-girlfriend replied: thank you.

"it's strange, why do you say you have something to look for on someone's birthday?" Ren Yifei thought it was strange that he had found their mutual friend.

"what happened to xxx?"

It took two minutes for the other party to respond, but the attitude was not very good: "you ask him, how do you know?"

"I've seen her. Did something happen to her on the way?" Ren Yifei added, "Don't get me wrong, you are just asking casually."

Sure enough, the unveiled clown bewildered the mutual friends over there, and they asked, "Don't you know?" Her family is bankrupt, her father is ill, and her mother is waiting for treatment in the hospital. If you still have a conscience, give her back the things she used to talk to you about. "

Ren Yifei concatenated this information and finally knew what the lead / fire / wire that detonated the deceased's ex-girlfriend was.

Even he knew the killer's modus operandi.

There is no need for a secret room at all. the killer used to live here, and it was easy to find a spare key. She even had a spare key herself.

After the decision was made, the killer came here and sneaked into the room.

She can put on shoe covers and gloves and hide in the guest room. Watching the deceased and his boyfriend have a good time. In addition, the killer also knew that the boyfriend would drink milk before Rest-it should have been known in advance, otherwise he would not have prepared sleeping pills or tranquilizers.

She sprinkled the medicine into the milk, shook it evenly and hid in the guest room.

Then, the deceased and his boyfriend went home, and they ate and washed as usual until the deceased boyfriend drank the milk adulterated. The murderer next door was tortured by hatred as he listened to the laughter over there.

The boyfriend of the deceased just felt sleepy and asked for Rest, and then they went to sleep.

At two or three o'clock in the morning, when people slept best, the killer put on something similar to a disposable protective suit, perhaps a hood, and then she went into the bed and killed the victim.

The boyfriend next to me felt it because of the medicine.

The killer came to the bathroom, washed the face sprayed with blood, and then packed up all the disposable things on his body to compress his very small volume.

She will put on new shoe covers and gloves and get out of here.

Disposable appliances can be burned directly, small blades can be thrown away, these are easy to deal with.

"there is a motive and a modus operandi, but what about the evidence?" Back to the beginning, he knew who it was, but he had proof. The police, the courts, it's all evidence.

Ren Yifei went to the kitchen first. he looked at the handle of the refrigerator and found that it was wrapped in a layer of frosted metal skin and could not leave fingerprints. Then he opened the refrigerator, and there was a layer of fog on the surface of the milk lid and the milk carton, which could not be removed with fingerprints.

"if the killer is more careful, he can wear gloves all the time, let alone leave fingerprints. Generally speaking, the murders of these murders are determined by the murderers' tools. If you can't get out, where can you find the tools to commit the crime? "

The murder weapon is still in the roof. It's not portable.

Throat cutting is done with slightly sharper blades, and small and exquisite blades can be carried with them, and the killer is stupid enough to leave such deadly evidence behind.

"Oh, it's so hard, it's too hard, it's so hard." Near noon, hungry and tired, Ren Yifei fell angrily on the sofa.

He reached for a pillow, pressed it under his head, curled up on the sofa and smelled of pity.

"Hmm?" All of a sudden, a half-long hair on the pillow attracted his attention.

This is a hair with a hair follicle, which means it is used for dna identification. This hair is about thirteen centimeters, the top inch is black, the bottom is bleached and dyed smoky gray, and the tip of the hair is stained with a little blood.

Ren Yifei immediately sat up with salted fish, turned on his cell phone and found out the moments of the deceased's ex-girlfriend. There were a lot of selfies on it, except that she had such long hair recently.

"Wow." He dialed Officer Liu's phone. "A whole roast duck," he said.

Officer Liu:. Huh?

"I found the proof you asked for."
